A man seriously injured in an accident at an Ocala car dealership Wednesday afternoon died later that day.

According to Ocala police, Spencer Halstead, 52, of Silver Springs Shores, died at Ocala Regional Medical Center at 4:19 p.m. Wednesday. Police said an autopsy conducted Thursday morning indicated his death was the result of a "medical issue," not the crash.

Halstead was driving a 2001 Honda CRV-4 east on Southwest 17th Street when he pulled onto the grassy shoulder at the entrance to Auto Max. He suddenly accelerated and the Honda struck the side of a Chevy truck that was on display, knocking it onto its side.

Officer Sean Young arrived and administered CPR on Halstead until Ocala Fire Rescue officials came to the scene. Assistant Fire Chief Brian Stoothoff said his agency received a call at 3:43 p.m. and arrived within three minutes.

Halstead was taken to Ocala Regional Medical Center in critical condition.

His wife, Dawn Halstead, 48, was a passenger in the vehicle. She was treated on scene by paramedics, then also was taken to ORMC in stable condition with what appeared to be a broken nose, officials said.
